Other comments have mentioned or hinted at this, but I think the only way to reduce the friction of online subscriptions is to "pool" the content a'la spotify or apple music. I would pay some amount per month for an all I can read premium content model just like I pay for music streaming. Having multiple magazines/providers to choose from would be a big draw for me as I am not always interested in the content of one provider. I like Wired and have read their articles on occasion. I even have a subscription to the print version that I got for airline points I couldnt use elsewhere. I cant see any other way for me to make the jump.
